2023 Jeep Grand Wagoneer

Overview
Before the Grand Wagoneer arrived, Jeep had never built an SUV so big and luxurious. Within its enormous shell are three rows and seating for up to eight, not to mention attractive materials and upscale features throughout. The long-wheelbase Grand Wagoneer L has more storage space behind all those seats, too. Unfortunately, the longer version also will be more difficult to maneuver than its already cumbersome counterpart. Regardless of length, the largest Jeep suffers from terrible fuel economy, with a combined EPA rating of just 16 mpg. That estimate isn’t for a big-displacement V-8, either, but a new twin-turbo six-cylinder with 510 horsepower. At least that engine should get the 2023 Jeep Grand Wagoneer and its precious cargo where it needs to go on time and in exceptional comfort. For those not looking to spend six figures, the Jeep Wagoneer is a less expensive, albeit less fancy, alternative.

What's New for 2023?
For 2023, the Grand Wagoneer L joins the lineup. Its wheelbase is seven inches longer than the standard Wagoneer, and it’s a foot longer overall. These extensions contribute to considerably more cargo space behind all three rows of seats. Under the hood, the long-wheelbase model has Stellantis’s new Hurricane engine, which is a twin-turbo 3.0-liter inline-six that makes 510 horsepower and 500 pound-feet of torque. While it is standard on the stretched Grand Wagoneer L, Jeep hasn’t said if the Hurricane will also be standard on its shorter counterpart, which previously only came with a 471-hp 6.4-liter V-8.

Pricing and Which One to Buy
Series I $90,000 (est)
Series II $100,000 (est)
Obsidian $106,000 (est)
Series III Premium $110,000 (est)

Jeep hasn’t yet announced pricing for the 2023 Grand Wagoneer lineup, but the company has said that it’ll go on sale in the second half of this year. With that said, we still think the Series II trim level looks to be the best value. It comes standard with 22-inch wheels, a two-tone roof, a 10.3-inch touchscreen for the front passenger, nicer leather-trimmed upholstery, a rear-seat monitoring system, and additional driver assists such as night vision and a semi-autonomous drive mode.

Engine, Transmission, and Performance
With the introduction of the new long-wheelbase Grand Wagoneer L comes a new engine. Dubbed the Hurricane, the 510-hp twin-turbo 3.0-liter inline-six pairs with an eight-speed automatic transmission and all-wheel drive. While this engine comes standard on the stretched Grand Wagoneer, Jeep hasn’t confirmed whether the short-wheelbase model will still offer the 471-hp 6.4-liter V-8 powertrain that was previously standard. As with its domestic rivals, the Grand Wagoneer utilizes body-on-frame underpinnings, in this case derived from the Ram 1500 pickup truck. However, the Jeep features an independent rear suspension rather than the truck's solid rear axle, which gives the SUV a smoother ride and better handling than the Ram. Along with several four-wheel-drive systems, the Grand Wagoneer offers an adaptive air suspension that can raise its ride height up to 3.6 inches or lower it by a half-inch. It also boasts 10 inches of ground clearance, up to two feet of water-fording capability, and a max tow rating of 9860 pounds. After driving the Grand Wagoneer, we appreciated its relaxed and refined ride on the highway; however, its pickup-truck structure contributes to a jiggly ride when pavement is less smooth. Likewise, the massive SUV isn't very agile in small spaces and suffers from notable body roll on curvy roads that is exacerbated by its light and vague steering feel.

Fuel Economy and Real-World MPG
The 2023 Grand Wagoneer L is rated at 16 mpg combined, with estimates of 14 mpg in the city and 19 mpg on the highway. Those figures are slightly better than the 6.4-liter V-8 that powers the 2022 Grand Wagoneer, which is rated at 15 mpg combined, 13 city, and up to 19 highway. When we have the chance to run a 2023 model on our 75-mph highway route, which is part of our extensive testing regimen, we can evaluate its real-world mpg.
